摘要： The invention relates to a method for demoulding a casting from a casting mould having at least one casting core which images a passage opening in the casting connecting two outer sides of the casting and is produced from a moulding material bound by a binder which decomposes under the influence of temperature, wherein the casting mould undergoes a heat treatment in a furnace for the demoulding, during which it is heated to a temperature at which the binder loses its binding effect.In the furnace, hot gas is flowed through a passage formed in the casting core of the casting mould the temperature of the hot gas corresponding at least to the temperature at which the binder of the moulding material loses it binding effect such that the casting core decomposes into fragments or separate sand particles as a consequence of the influence of the hot gas.
